I have a method run() error!

I have written the following code below, but I have this error "JavaTester.java:123: error: variable response is already defined in method run()", anybody know how I can fix this? Thanks in advance!

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

String response;

do {
  String response = console.readLine("Do you understand do while loops?");
  if (response.equalsIgnoreCase("no")) {
  }
} while (response.equalsIgnoreCase("no"));

String response;

do {
  response = console.readLine("Do you understand do while loops?");
  if (response.equalsIgnoreCase("no")) {
  }
} while (response.equalsIgnoreCase("no"));

You don't put "String" in front of the second "response" because is declaring a new variable called "response" which you already have, which is why you got the original error.

Hi Farouk,

Try deleting 

String response;

In your very first line. Hope that helps. If not please let me know.
